A lack of preparation and correct outdoor footwear has been cited as the main reason for a recent mountain rescue operation in Snowdonia.

The two students were found stuck on Tryfan's North Ridge at approximately 19:00 BST, after setting off unprepared earlier in the afternoon at 14:00 BST.

Ogwen Valley Mountain Rescue organisation was alerted after the man and woman rang 999, claiming that they were lost and could not descend the climb safely.

Speaking to Grough, Chris Lloyd from the rescue team said:"These two young people were totally ill equipped for the scramble up the North Ridge.

"They were dressed in town clothes and wearing trainers."

Rescuers criticised the pair for placing a strain on volunteer rescuers and limited resources, after assisting the students by lowering them onto a safe footpath.

Tryfan is one of 14 peaks in Snowdonia and is well known for its rough terrain at over 3,000 ft.
